Frequently Asked Questions.

Here are some of the frequently asked questions and their best answers for your clarification.

What does a fractional CFO actually do?
A fractional CFO provides the same financial leadership as a full-time CFO, including cash flow forecasting, financial modeling, investor reporting, KPI development, and strategic planning, but on a part-time or project basis. You get senior-level financial guidance without a full-time salary commitment.
You probably need one when your financials are slowing down decisions, when you’re preparing to raise capital, when investors start asking questions you can’t answer confidently, or when your books are clean but you have no idea what the numbers mean for the next 12 months.
Most engagements run between $3,000 and $12,000 per month depending on the scope of work, how often you need support, and the complexity of your business. Compare that to a full-time CFO salary that averages $400,000 or more annually, and the value is clear for most growing companies.
We complement your existing team. We help founders build the financial models, investor-ready reports, and projections that VCs and institutional investors expect to see. We also help you understand your unit economics and cash runway before you walk into a pitch.
A bookkeeper records transactions. An accountant handles compliance and tax filings. A CFO uses all of that to drive business strategy. If your books are clean and taxes are filed but you still do not know if you can afford to hire, raise prices, or expand, that is the CFO gap.
Yes. We work alongside your bookkeeper, CPA, and internal team. The goal is to fill the strategic gap without disrupting what is already working. Most clients find that having a CFO involved actually makes their other financial team members more effective.
